Abstract: Activated coke from rhenish lignite coal is a reasonably priced adsorption material for the purification of flue gas from a waste incineration plant. This study examines the adsorption and desorption behaviour of mercury (Hg) and mercury(II)chloride (HgCIZ) on coke. For that purpose coke samples were loaded with Hg and (HgCI2) in a laboratory facility. Additional to untreated coke, sulphuric acid impregnated coke was used too. The examinations of desorption were conveyed through thermal analysis and mass spectrometry. The adsorption quality of the coke for mercury species is strongly increased by impregnation with sulphuric acid. The desorption ofHg begins at 150°C. Heating up to 500 °C under inert gas conditions is a simple method for entire desorption
